Nature's forms are frilly, flexible, and functional
Kenneth K. Yamamoto, Toby L. Shearman, Erik J. Struckmeyer +2
A ubiquitous motif in nature is the self-similar hierarchical buckling of a thin lamina near its margins. This is seen in leaves, flowers, fungi, corals, and marine invertebrates.…
Computing with non-orientable defects: nematics, smectics and natural patterns
Chiqun Zhang, Amit Acharya, Alan C. Newell +1
Defects are a ubiquitous feature of ordered media. They have certain universal features, independent of the underlying physical system, reflecting their topological origins. While…
Continuum mechanics of moving defects in growing bodies
Amit Acharya, Shankar C. Venkataramani
Growth processes in many living organisms create thin, soft materials with an intrinsically hyperbolic geometry. These objects support novel types of mesoscopic defects - discontin…
Buckling sheets open a door to understanding self-organization in soft matter
Shankar C. Venkataramani
This is an invited commentary on "Geometrically incompatible confinement of solids", B. Davidovitch, Y. Sun and G. M. Grason (PNAS, doi:10.1073/pnas.1815507116 , arxiv:1809.06919).
Isometric immersions, energy minimization and self-similar buckling in non-Euclidean elastic sheets
John Gemmer, Eran Sharon, Toby Shearman +1
The edges of torn plastic sheets and growing leaves often display hierarchical buckling patterns. We show that this complex morphology (i) emerges even in zero strain configuration…
Isometric immersions and self-similar buckling in Non-Euclidean elastic sheets
John Gemmer, Eran Sharon, Shankar Venkataramani
The edge of torn elastic sheets and growing leaves often form a hierarchical buckling pattern. Within non-Euclidean plate theory this complex morphology can be understood as low be…
